This reference design is capable of charging two devices at 2.5A each with over 82% efficiency. The UCC24610 synchronous rectifier controller and CSD17312Q5 FET reduce the rectifier loss and provide high efficiency with a minimal increase in cost. The TPS2561A provides accurate and independent current limit protection for each port. The TPS2513 communicates with the mobile device under charge to ensure that the charger is accepted by most phone and tablet models. This compact design consumes a volume of only 2.15" x 1.7" x 1.0".
